ios - 退出全屏后 MPMoviePlayerController 缩放模式问题

Question

我只是使用 MPMoviePlayerController 播放视频...我的代码是

-(void)playMovie:(NSURL *)url
{
    moviePlayer =
    [[MPMoviePlayerController alloc]
     initWithContentURL:url];
    if (IDIOM==IPAD) {
        [moviePlayer.view setFrame:CGRectMake(22,100, 720, 300)];
    }
    else
    {
        (IS_IPHONE_5)? [moviePlayer.view setFrame:CGRectMake(22, 70, 280, 150)]:[moviePlayer.view setFrame:CGRectMake(22, 40, 260, 140)];
    }
    [_scrollView addSubview:moviePlayer.view];
    moviePlayer.scalingMode =MPMovieScalingModeFill;
    [moviePlayer prepareToPlay];
    [moviePlayer play];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayerDidEnterFullscreen:) name:MPMoviePlayerDidEnterFullscreenNotification object:Nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayerDidExitFullScreen:) name:MPMoviePlayerDidExitFullscreenNotification object:Nil];

}

-(void)moviePlayerDidEnterFullscreen :(id)sender
{
    NSLog(@"fullscreen");
   [moviePlayer play];
    moviePlayer.scalingMode =MPMovieScalingModeFill;

}

- (void) moviePlayerDidExitFullScreen:(id)sender {

    NSLog(@"exit full screen");
    [moviePlayer play];
    moviePlayer.scalingMode =MPMovieScalingModeFill;

}

这里，当我最初播放视频时，视频将处于“MPMovieScalingModeFill”模式...但我的问题是，如果我按全屏，它会全屏显示视频。当我按“退出”“全屏”时，我的视频模式将变为到“MPMovieScalingModeAspectFit”模式。但我需要始终处于“MPMovieScalingModeFill”模式。我的代码有什么问题......请帮助我......

我相信这会生成 MPMoviePlayerScalingModeDidChangeNotification。

[[NSNotificationCenter defaultCenter] addObserver:self 
                selector:@selector(movieScalingModeDidChange:) 
                name:MPMoviePlayerScalingModeDidChangeNotification 
                object:nil];

MPMoviePlayerScalingModeDidChangeNotification

当电影播放器​​的缩放模式改变时发布。没有 userInfo 字典。 缩放模式可以通过编程方式或通过用户交互进行更改。要设置或检索电影播放器​​的缩放模式，请访问其 scalingMode 属性。状态已更改的电影播放器​​可用作与通知关联的对象。
